DUMPING DEVICE.

Application filed. March 10, 1925. Serial No. 14,531.

To all whom it may concern Be it known that I, EDGAR D. Cannon, a citizen of the United States, residing at Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Dumping Devices; and I do hereby declare the following to be a full,.clear, and exact description of the invention, such as will enable tains to make and use the same.

This invention is an improvement in vehicle dumping devices of the class in which a tilt-able platform is operated by means l5 of a fluid pressure cylinder located in a pit beneath the platform.

My improvement relates particularly to the fluid pressure cylinder and means by which it is mounted.

The objects of my arrange the cylinder, which is preferably of the telescopic type, that it can be easily and quickly placed in operative position in the pit and be easily removed therefrom without the use of skilled labor and without the necessity of unfastening' bolts or nuts.

A further object of my improvement is to provide the lower and upper pads or hearings that take the thrust of the cylinder and piston rod, with removable cushioning members of wood or other easily replaceable material so as to better distribute the bearing load and produce quieter and smoother action when the platform is raised and lowered.

lVith the foregoing and certain other obj ects in view which will appear later in the specifications, my invention comprises the devices described and claimed and the equivalents thereof.

In the drawings Fig. 1. is a diagraiumatic view showing the arrangement of the parts in side elevation.

Fig. 2 a perspective view of the tele' scoping cylinder extended.

" is a perspective of the lower pad invention are to so O and bearings.

Fig. 4 is a side view of the cylinder retracted.

Fig- 5 is a perspective view of the upper pad.

others skilled in the art to which it apper- Since the fluid connections and the source of pressure do not constitute part of my invention and are well known in the art, they are omitted from the drawing.

Numeral 1 designates the usual pit and 2 the tiltable platform carrying the vehicle to be dumped. 3 is the telescopic cylinder trunnioned at the bottom to a pad a. A second pad 5 secured to the under side of 69 the platform forms a seat for the upper rounded end 6 of piston rod 7 The bottom head 8 of the cylinder is pro vided with a pair of laterally extending trunnions 9, 9, between which is the rounded projection 10. The trunnions 9, 9 lit in bearings 11 of the pad 4 and the projection 10 fits in a recessed cushioning member 12 of wood or similar suitable material seated on pad 4 between the bearings 11, as shown in Fig. 3. Similarly, the upper pan 5 has a recessed cushioning member 13 which is located between the two side lugs let, 14, between which the upper rounded end 6 of piston rod 7 is removably received.

The telescopic cylinder enables a shallow pit to be employed, and the pads a and 5 with their cushioning members 12 and 13 enable the cylinder when under load to properly adjust and take its hearing so as 39 to avoid undesirable side thrusts and twisting stresses in the operating, parts of the cylinder.

lVhen the tilting platform is not used the cylinder can be immediately detached and S lifted from the pit without the necessity of unfastening' bolts or nuts. Consequently rusting of the parts will not interfere with the ease of removing and replacing the cylinder. 7 J0 By this arrungemcnt one cylinder may be employed, to serve a number of unloading platforms that are to be used in succession, as in sugar beet factories and similar locations. 7

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

In a device of the class described including; a pit and a tiltable vehicle platform,

a telescopic fluid pressure cylinder having lateral trunnions on the head thereof, and

a projection therebetween, a bearing pad having a pair of trunnion-bearings spaced apart and a bearing socket member for said projection therebetween, bearing pad se- 5 cured to the under side of said platform and having a socketed bearing member, said pads and socketeci bearing); members comprising means whereby the telescopic c rler der 'is releasably seated in operative set!- alining position, for the purposes set forth. 10

In testimony whereof, I aflix my signature.
